Abstract
Non-coding RNAs (ncRNAs) are a large class of important regulatory molecules involved in many physiological and cellular processes. Small nucleolar RNAs (snoRNAs), a subset of the small ncRNAs, are molecules located in the cell nucleolus. Even though, they are one of the most ancient and evolutionary conserved ncRNAs, they are gaining more prominence and attention in the recent years only. The classical function of snoRNAs is to act as guide RNAs of rRNAs and nucleolytic processing of the rRNA transcripts. However several scientific evidences have indicated that other than the classical functions, they are involved in multiple functions such as metabolic stress regulation, modulation of alternative splicing, controlling cell behavior, etc. and the dysregulation of snoRNAs could contribute to carcinogenesis. Even though many independent works have been carried out, to examine the role of snoRNAs in several human diseases including cancer, specific projects to study the cumulative role of snoRNAs in a disease is limited. The advent of high throughput and deep sequencing technologies has opened up new avenues for carrying out such studies. This study focusses on the utilization of snoRNAs as potential biomarkers characteristic to ovarian cancer based on a RNA-Seq data. We have downloaded a transcriptome data, [PRJNA209481] from the NCBI BioProject, pertaining to human ovarian cancer cell lines. Downstream analysis was done by Tuxedo pipeline of RNA-Seq data analysis. The differential expression analysis by Cuffdiff threw a total of 847 differentially expressed genes, of which we found, 71 snoRNAs to be up regulated and 34 snoRNAs as down regulated. Many of the previously reported snoRNAs having a role in tumorigenesis in a variety of cancers are also seen to be dysregulated in this study. Further investigation is underway to analyze the effect of differentially expressed snoRNAs in ovarian cancer and their potential as biomarkers.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
